Been there had that no fun, our family Dr aka the quack lol was going to put me in physical therapy after 2 weeks of doing stretches and such. It would take me 30 minutes to get out of the car at work and the same when I got home. I found an old school chiropractor and went to him . Oh my what a difference, the wallet and the stretches all good info , but for me getting my frame straightened was the ticket. My neighbor growing up was a Chiropractor thats why I said old school hands on . Now once I feel it coming on I go get cracked before the muscles setup out of position. You may want to get that neck checked out , you may just need a adjustment . Good luck my friend its a rough deal, got to get rid of the pain to get rid of the inflammation ,got to get rid of the inflammation to get rid of the pain. Hard to do .
